Lay the foundations for a greener future at your company with our durable, low-carbon Marine Crete. From turbine foundations to marine anchoring, our market-leading solution is designed with circularity in mind – providing a cleaner answer to future structural subsea questions.
Sustainable construction: build a positive marine legacy
This low-carbon alternative to traditional Portland cement is versatile, strong and is well suited to applications both above and below the water.
It’s made with our alkali-activated mix, advanced casting techniques and with the ability to manufacture on-site, Marine Crete offers an incredibly low carbon footprint, and we’ll work with you to deploy it as efficiently as possible.
Marine Crete will help you to build resilient foundations above and beneath the waves, that once decommissioned, can be left indefinitely to become part of the marine ecosystem - helping you to negate costly and environmentally damaging decommissioning work.Get in Touch

“Kier have been very satisfied and pleased with ARC Marine throughout the preconstruction and construction stages of the Newlyn Tidal R&D project. ARC Marine have fabricated and delivered exceptional Intertidal reef cube® ECO armour units for the project where all parties, including Kier, the Environment Agency and Atkins, have been very impressed with the quality of finish of the units. Overall a very exceptional service from ARC Marine and would highly recommend.”
“reef cubes® is a unique product that could reach a massive global market. Marine-i has been proud to help ARC Marine develop and test their amazing new approach to marine conservation and in particular, its application to marine renewable energy. Their pioneering products have the potential to improve the health of our oceans for generations to come.”
"ARC Marine are providing 25% of the reef blocks for the Newlyn project. Their blocks offer multi-functional benefits, such as biodiversity enhancing design and low-carbon fabrication. The development of viable alternatives to carbon intensive and non-sustainable solutions such as reinforced concrete, or quarried rock, is hugely important in order to meet the EA’s organisational targets to achieve net zero by 2030. More broadly, decarbonisation of the coastal and subsea infrastructure industry will also provide an important contribution to wider UK pledges on climate change."
“The idea of a carbon-neutral reef cube® that can be used to help rehabilitate reef ecosystems is exciting – we really need to do everything we can to give coral reefs a break”
